Drill Subs (Thread Adapters)

Drill subs are an important integral part of everyday drilling. Not having the right thread adapter can make your life miserable. We have a large inventory of common and not so common sizes. Custom sizes are always available.

Installing a float sub (with check valve) is always a good idea when drilling in wet situations.
